The phrase combines the German word for universe with ultrageil, slang for something extremely good or exciting, which explains its use as maximum praise online. Without a single confirmed source clip behind it, the sound spread as a generic meme reaction on short form video and soundboards, shared for its foreign language punch and dramatic energy. German speaking creators helped popularise the wording, while international editors adopted it because the meaning is clear from the tone alone, even without translation, keeping it in rotation for hype edits.
